how many degrees of total timing do you have @ 10psi?
16deg base timing, how much do you advance max in the upper rpm's @ 10psi?
I'm trying to get an idea if my timing maps are too conservative..... just a ballpark for the next tuning session on the dyno.....

just dont pull to much timing out cause then you will start melting stuff.............. no good! and if you dont have a good understand of what timing acutally is then i would do some research. that will tell you a lot

about 15* total on a D16. I dont see what the psi has to do with it though. What if I have a t25 and the next guy has a sc61? Also bore diameter will play a big role in how much timing is appropriate.

About 19 degree on the low speed cam, about 23 on the high speed cam. (Those are total timing numbers....running hondata)

im going to say somewhere roughly between 20 and 22ish degrees total. that comes out to be around 6-8 degrees taken out, which divided by 10 psi is like about .7 degrees/lb, which is acceptable i think.
my z6 map had me running 20* at 10.41 psi @redline on uberdata(just a hair over 8* taken out)

exactly. It doesn't matter what Joe's timing was @ X psi if the setups are different. You tune an engine according to MBT, not psi. Timing can vary.
